About
Test your limits at the Bear Lake Ultra, a genuine test of mental and physical endurance in Lapeer, Michigan, where you complete as many loops as possible over a varied course combining singletrack, wide trails, grassy stretches, and bridges, all within a continuous 24-hour window. Open to both runners and walkers, the event supports you with a fully stocked aid station offering a range of refreshments, plus on-site amenities like heated restrooms and convenient camping right next to the course. Strategic breaks and the option to bring a pacer after reaching certain milestones give you every chance to push your limits.
